On October 19th, 2015 Archery Talk implemented some new classified user requirements.

First, a new user will have to wait two weeks before they will be able to start a classified ad.

Second, a user must have at least 20 posts prior to starting a classified ad. This will go for all users, if you have been a user for two years and have 10 posts, you will not be allowed to start a classified thread until your post count is at least 20.
Please be aware that it takes a little time for the server to recognize and reset your permissions once you have met those two criteria. Please be patient.

Let me help you out...

Let me first give you mine. I shoot both the carbon express terminator hunters at 487 grains and the easton axis arrows at 435 grains.

Carbon Express:
246 fps x 246 fps x 487 grains/450240 = 65.4 KE

Easton Axis arrows:

260 fps x 260 fps x 435 grains/450240 = 65.3 KE

The heavier arrow carries more KE shot from the same bow at the same poundage, but the speed will be higher for the lighter arrow and an insignificant amount of KE lost.

Contact Javelina on this site and he'll give to you the formula for momentum. This is more important for your information in shooting animals with arrows.

My momentum for the carbon express was equal to .54 or something like that.

BACK TO YOUR QUESTION:

Is speed more important than weight--no
Is weight more important than speed--no

Are both equal in consideration--MY OPINION--yes.

Lets look at shooting an arrow for grins and giggles using my bow weight of 85#'s. Lets say that I'm pretty insane and want to shoot an arrow about 4 grains per pound. Thats an arrow that weighs 340 grains. Lets use for the sake of an insane arguement an arrow that weighs 350 grains.

Here we go. Lighter arrow at 350 grains = 277 fps.
(by the way I have a 26" draw)

277 fps x 277 fps x 350/450240 = 59.6 lbs of KE.

Now obviously I would not shoot an arrow that was only 4 grains per pound but I used this to compare what a light arrow would do in KE vs. an heavier arrow.

I love both my arrows and even though I have not shot anything with the axis arrows they still out penetrate my heavier carbon express arrows.

With that said, on October 15, 2003 I shot my very first buck in my very first year hunting at 38 yards with a complete pass thru using the heavier arrows.

I have always used the formula that Newhunter is talking about . This formula works great . Want to see a good thread on kenetic energy ? Check out this one Javi posted http://www.archerytalk.com/vb/showt...&threadid=50169
